Stockholders' Equity Note [Abstract] |  |
STOCKHOLDERS EQUITY | 9. Stockholders’ Deficit SPAC Warrants Upon the completion of the Business Combination, the Company assumed the Private Warrants and the public warrants to purchase Common Stock, each with an exercise price of $402.50 per whole share (the “Public Warrants”, and together with the Private Warrants, the “SPAC Warrants”). Holders of the SPAC Warrants are entitled to acquire shares of Common Stock. The SPAC Warrants will expire five years after the completion of the Business Combination or earlier upon redemption or liquidation. If the reported last sale price of the Common Stock equals or exceeds $630.00 per share for any 20 trading days within a 30-trading day period ending three business days before the Company sends the notice of redemption to the warrant holders, the Company may redeem all the Public Warrants at a price of $0.01 per warrant upon not less than 30 days’ prior written notice. If the Company calls the Public Warrants for redemption, the Company will have the option to require all holders that wish to exercise the Public Warrants to do so on a cashless basis. The Company will not be required to net cash settle the SPAC Warrants. The Public Warrants are equity-classified warrants and recognized in additional paid-in capital in the accompanying consolidated balance sheets. The Private Warrants are liability-classified warrants and are recognized as liabilities (refer to Notes 1 and 4). During the year ended December 31, 2023, the SPAC Warrants held by Sorrento were repurchased, and certain of such warrants transferred to Oramed, as a result of the Sorrento SPA (refer to Note 8). On September 20, 2024, the Company repurchased 4,000,000 of the SPAC Warrants (which are currently exercisable for an aggregate of up to 114,286 shares of Common Stock) held by Oramed (refer to Note 7). Following the repurchase, these warrants were cancelled. As of each of March 31, 2025 and December 31, 2024, 5,467,692 Public Warrants, which are currently exercisable for an aggregate of up to 156,220 shares of Common Stock are outstanding. As of each of March 31, 2025 and December 31, 2024, 1,000,000 Private Warrants, which are currently exercisable for an aggregate of up to 28,572 shares of Common Stock are outstanding. Preferred Stock The Company is authorized to issue 45,000,000 shares of preferred stock (the “Preferred Stock”) of which there are two series in total. Series A Preferred Stock As of March 31, 2025 and December 31, 2024, there were 29,057,097 shares of Series A Preferred Stock outstanding. On September 21, 2023, the Series A Preferred Stock was repurchased and derecognized for accounting purposes. The Series A Preferred Stock is currently held as collateral for the Oramed Note. Series 1 Preferred Stock On October 27, 2024, the Board declared a stock dividend (the “Dividend”) consisting of an aggregate of 5,000,000 shares (the “Dividend Stock”) of Series 1 Mandatory Exchangeable Preferred Stock, par value $0.0001 per share, of the Company (the “Series 1 Preferred Stock”) to record holders of certain of the Company’s securities as of the close of business on November 7, 2024 (which date was subsequently changed to such later date to be determined in the sole discretion of the Board) (such later record date as so determined by the Board, the “Record Date”). Pursuant to the Certificate of Designation of Preferences, Rights and Limitations of Series 1 Mandatory Exchangeable Preferred Stock (the “Certificate of Designation”) filed with the Secretary of State of the State of Delaware on October 28, 2024, the Series 1 Preferred Stock ranks senior to the Common Stock but junior to all other series of Preferred Stock with respect to distributions of assets upon voluntary or involuntary liquidation, dissolution, or winding up of the affairs of the Company. The holders of Series 1 Preferred Stock may become entitled to a pro rata portion of the number of shares that represents the lesser of (a) 10% of the shares of the Semnur Common Stock (or such other securities into which or for which such stock may be exchanged or converted), held by the Company as of immediately prior to the Effective Time (as defined below) (taking into account any adjustment for any stock dividend, stock split, reverse stock split or similar transaction) and (b) that number of shares of Semnur Common Stock (or such other securities into which or for which such stock may be exchanged or converted) equal to $200,000,000 divided by the closing price of such Semnur Common Stock (or such other securities into which or for which such stock may be exchanged or converted) on any national securities exchange on which such shares are listed on the date that is 10 trading days prior to the Determination Date (as defined below), which shares shall be paid from the shares of Semnur Common Stock (or such other securities into which or for which such stock may be exchanged or converted) held by the Company as of immediately prior to the Effective Time (taking into account any adjustment for any stock dividend, stock split, reverse stock split or similar transaction). Furthermore, the holders of Series 1 Preferred Stock shall not be entitled to receive any dividends and shall not have any voting rights by virtue of their ownership of any shares of Series 1 Preferred Stock. For purposes of the Certificate of Designation, (a) “Effective Time” means the effective time of the Semnur Business Combination as determined under the terms of the Semnur Business Combination Agreement, (b) “Determination Date” means, if the Semnur Common Stock (or such other securities into which or for which such stock may be exchanged or converted) is listed for, and trading on, any national securities exchange, the date that is 15 trading days following the Registration Date, (c) “Registration Date” means the earlier of (i) the Effective Time, at which time the shares of Semnur Common Stock (or such other securities into which or for which such stock has been exchanged or converted) are registered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and (ii) the time at which the Registration Statement is declared effective by the SEC and (d) “Registration Statement” means a registration statement, whether under the Exchange Act, or the Securities Act of 1933, as amended (the “Securities Act”), that is filed by Semnur or any successor thereto or affiliate thereof with respect to the registration of the Semnur Common Stock or any securities into which or for which such stock may be exchanged or converted. The Board has the right to change the Record Date and the right to revoke the Dividend at any time prior to the payment date therefor. There can be no assurance that the Board will not revoke the Dividend or that, even if such Dividend is paid, the conditions for the mandatory exchange set forth in the Certificate of Designations will ever occur (including that the Registration Date shall have occurred on or before 11:59 p.m. Eastern time on October 28, 2025). The Series 1 Preferred Stock does not have any bifurcated features and is classified in equity at par value because the Company had an accumulated deficit position as of Dividend Stock declaration date. As of March 31, 2025 and as of the date of this filing, none of the Dividend Stock or any shares of the Series 1 Preferred Stock were issued or distributed. Treasury Stock As of March 31, 2025 and December 31, 2024, there were 1,458,263 and 1,716,245 shares of Treasury Stock, respectively. At-the-Market Sales Agreement On December 22, 2023, the Company entered into the ATM Sales Agreement with the Sales Agents, which agreement was voluntarily terminated by the Company effective as of March 5, 2025. Pursuant to the ATM Sales Agreement, the Company was able to offer and sell the ATM Shares through or to the Sales Agents. The Company had no obligation to sell any shares of Common Stock under the ATM Sales Agreement and may suspend offers at any time. The ATM Shares offered and sold in the ATM Offering were issued pursuant to the Company’s shelf registration statement on Form S-3 (which was initially filed with the SEC on December 22, 2023, as amended, and declared effective on January 11, 2024 (File No. 333-276245)) (the “Shelf S-3 Registration Statement”). The ATM Shares were offered only by means of a prospectus forming a part of the Shelf S-3 Registration Statement. The Sales Agents were entitled to a commission equal to 3.0% of the gross proceeds from each sale of shares of Common Stock. The Company agreed to reimburse the Sales Agents for certain expenses and has agreed to provide indemnification and contribution to the Sales Agents against certain civil liabilities, including liabilities under the Securities Act. During the three months ended March 31, 2025, no sales of Common Stock had been made under the ATM Sales Agreement. During the three months ended March 31, 2024, the Company sold 2,637 shares of Common Stock pursuant to the ATM Sales Agreement for net proceeds of approximately $0.1 million.

The securities in the February 2024 BDO were offered and sold by the Company pursuant to the Shelf S-3 Registration Statement, a base prospectus dated January 11, 2024, and a final prospectus supplement dated February 29, 2024. The February 2024 BDO closed on March 5, 2024, and the combined price per February 2024 BDO Firm Share and accompanying February 2024 BDO Firm Warrant paid by the underwriters was $54.74, which amount reflects the combined public offering price of $59.50, less underwriting discounts and commissions. Subject to certain ownership limitations, the Common Warrants are immediately exercisable, set to expire five years later, with an exercise price of $59.50 per share, subject to adjustments. Additionally, the Company issued the representative warrants (the “February 2024 BDO Representative Warrants”) to the underwriters, allowing them to purchase up to 13,446 shares of Common Stock, with these warrants being immediately exercisable at $74.38 per share, representing 125% of the combined public offering price per February 2024 BDO Firm Share and accompanying February 2024 BDO Firm Warrant. The Company accounted for the February 2024 BDO Firm Warrants as a liability classified instrument (see Note 4) and the February 2024 BDO Representative Warrants as an equity classified instrument. The February 2024 BDO Representative Warrants are recognized in additional paid-in capital in the Company’s consolidated balance sheet.

The ATM Shares offered and sold in the ATM Offering were issued pursuant to the Company’s shelf registration statement on Form S-3 (which was initially filed with the SEC on December 22, 2023, as amended, and declared effective on January 11, 2024 (File No. 333-276245)) (the “Shelf S-3 Registration Statement”). The ATM Shares were offered only by means of a prospectus forming a part of the Shelf S-3 Registration Statement. The Sales Agents were entitled to a commission equal to 3.0% of the gross proceeds from each sale of shares of Common Stock. The Company agreed to reimburse the Sales Agents for certain expenses and has agreed to provide indemnification and contribution to the Sales Agents against certain civil liabilities, including liabilities under the Securities Act. As of December 31, 2024, the Company sold 78,975 shares of Common Stock pursuant to the ATM Sales Agreement for net proceeds of approximately $2.7 million.

The February 2024 BDO closed on March 5, 2024, and the combined price per Firm Share and accompanying February 2024 BDO Firm Warrant paid by the underwriters was $54.74, which amount reflects the combined public offering price of $59.50, less underwriting discounts and commissions.
